T0 @ZZ whom t may concern:

Be itknown that I, EDWARD HETT, a citizen of the United States, and a resident of New York, (New Dorp,) in the county of Richmond, State of New York, have invented certain new and useful Improvements in Controlling- Engines for Presses, of which the following is a specification.

My invention relates to presses, and more especially to devices for controlling the movements of parts of the mechanism in such presses-as, for example, for controlling the movements, in a lithographie press, of the printing-surfaces, the inking mechanisms, and the damping mechanism into and out of operative position.

It has for its object to provide means for controlling the movements of parts of presses, especially movements of parts of the press into and out of operative position, to effect such control more easily, efficiently, and with greater precision and certainty than has heretofore been possible, and preferablyto do this automatically and without requiring a change in the direction of the motive power.'

It consists of certain features of 'construction and combinations of parts herein shown and described.

I will now proceed to describe the preferred form of my improved device, shown in the drawings, in which the same reference-numbers in different figures refer to corresponding parts.

Figure l is a side elevation of my improved device in its preferred form. Fig. 2 is a plan with certain parts omitted and showing in adin my application for a patent filed on the lst day of June, 1896, known as SerialNo. 503,796; but I do not limit my improved devices here shown and claimed to use in such a press, as it is evident that they can be employed in connection with any lithographie or other press in which rollers for printing, inling, damping, or any similar purpose, or other parts of the press are to be moved-'as, for example, toward and away from an impression or printing surface.

In the operation of the multicolor-press in connection with which my improved devices are here shown and described it is necessary to move the entire series of printing-surfaces out of or into contact with the impressionsurface, to move the inking mechanisms out of or into contact with the printing-surfaces by swinging the ink-frames carrying the inking mechanism, and to move the damping mechanisms out of or into contact with the printing-surfaces by swinging. the dampingframes carrying the damping mechanisms, and it is in connection with these movements and to control them that my improved devices are herein shown and described.

In the preferred form of my improved controlling-engine shown and described herein I employ connecting mechanism or mechanisms between the driving mechanism of the controlling-engine (hereinafter referred to) and the part or parts of the press to be moved, connecting the said driving mechanism with the said part or parts of the press, driving' mechanism preferably driven by the driving mechanism of the press for imparting modition a shaft'to turn thecam-shatt, adapted to be operated by hand, as hereinafter described. Figs. 3, 3, 4, 4a, 5, 5, 6, 7, 7a, 8, 8a, and 9, and Figs. 3b, 4b, 5b, 6b, 7", 8b, and 9b, illustrating the first, second, third, fourth, fifth, sixth, and seventh operations, are diagrammatic to illustrate the operation of the various camsLclutches, and gear-Wheels upon one another and the effects produced thereby upon the parts of the printing mechanism of the press. Fig. lO is a detail of pawl 3l4 and wheel 32 and their connections.

My improved devices are primarily intended to be used with and are here described as appartenant to a multicolor lithographie printing press such asis shown and described tion through the said connecting mechanism or mechanisms to the said part or parts of the press to be moved, and suitable clutch mechanism, preferably automatically operated, to connect and disconnect the driving mechanism of the controlling-engine with some suitable source of power, preferably the driving mechanism of the press and to connect the said driving mechanism ofthe controllingengine with the said connecting mechanism or mechanisms and to disconnect them. I prefer to use in my controlling-engine driving mechanism which is capable of motion in either direction, as I am thus enabled by the Ause of the same controlling mechanism to impart to the part or parts of the press to be IOO moved a movement one way or the other, as desired. Such'movementoneway. or the other I obtain by employing, preferably between the source of power and the driving mechanltrolling-engine to move the part or parts of the press one `way and in the otherof said positions to impart motion in the opposite direction to the driving mechanism of the controlling-engine to move the said part or parts of the press the other way. AMy preferred form of mechanism for this purpose is shown in the drawings and consists of two clutch gear-wheels intermediate between the source of power and the main shaft of my controllingengine and a clutch adapted to cause one or the other or neither of the clutch gear-wheels y to connect the source of power with the said shaft, although, of course, any other mechanism suitable for the purpose maybe employed.l l

I will now proceed to describe the particular form of controlling-engine shown inthe drawings herein. l Q

1 represents the framework of the press.

2 is a shaft adapted to rotate in either direction, having loosely mounted upon it a number of gear-wheels 3, 4, and 5. These gear-wheels are capable of connecting shaft 2 with trains of gearing connected with dilTerent parts of the press to` be moved, such-as the damping or inking mechanisms'or the printing-cylinders, for the purpose of moving such parts in a manner and for purposes presently to be described, or of disconnecting shaft 2 from such trains of gearing.y Shaft 2 carries with it in its rotation a number of clutches 6 7 8, which clutches rotate with the shaft, but are splined thereon, so as to be capable of motion longitudinally along the shaft,-u and are adapted, as will be hereinafter described, to make contact.with gearwheels v3, 4, and 5, respectively, so as to cause the gear-wheels then to rotate with the shaft. For the sake of brevity shaft 2 will hereinafter be generally spoken of as the clutch-shaft.

3a, 3b, and 3c form a train of gearing meshing with bevel gear-wheels 3 and transmitting motion from shaft 2 through gear-wheel 3to frames carrying the damping-rollers. Such frames and damping mechanism are not here shown in detail, but are illustrated as to their, mode of operation in the operations shown upon Sheet 3 of the drawings, where 3erepre- 1 sents a damping-roller at the end of swinging frame 3d., mounted upon the shaft of 3f.

vWhen bevel gear-wheel 3 rotates with shaft from the form-cylinder, as shown in the third operation on the samey sheet. In the same way 4a represents atrain of gearing meshing with bevel gear-wheel 4 and transmitting motion to frames carryingl the inking-rollers. These are not shown in detail, but are illustrated in .the operations shown upon Sheet 3,

where 4d 4Ll represent inking-rollers supported upon a swinging frame 4C, mounted upon shaft 4b. The inking-rollers are similarly swung against or away from form-cylinder 5d as bevel gear-wheel 4 revolves one way or the other with clutch-shaft y2, as shown in the second and seventh operations,respectively. In the same way 5, 5b, and 5c represent a train of gearing meshing with spur-wheel 5 and transmitting motion to supports carrying the vprinting or form cylinders. -These are not shown in detail; but for purposes of illustration the printing or form cylinder is shown in seven operationsupon Sheet 3 as cylinder 5d. As gear-wheel 5 is rotated one way or the other by shaft 2 form-cylinder 5c1 is swung against or away from the drum or impression cylinder 5e, as shown in the fourth and seventh operations, respectively.

Motion in one direction or the other is imparted .to shaft 2 by the following-described mechanism:

9 is the main power-shaft and carries on its end bevel-gear 10, which meshes with bevelgear 11 on shaft 12. The latter shaft has at its other end bevel-gear 13. .Intermediate betweeny this driving mechanism and shaft 2 are two beveled clutch gearwheels 14 14, facing each other and loosely mounted upon shaft 2. They mesh with bevelgear-wheel13.

15 is a double clutch splined upon shaft 2, so as to` permit of longitudinal motion along the shaft, but adapted to rotate with the shaft. When this clutch remains midway between bevel gear-wheels 14 14, as shown in Fig. 2,-

shaft 2 does not revolve. When the clutch is movedto the right, in a manner to be presently described, it grips one of the gear-wheels 14, and thereby causes shaft 2 to rotate; but when the clutch is moved into contact with the other gear-wheel 14V it causes shaft 2 to be rotated in lthe opposite direction. Thus IIO 'while shafts 9 and 12 always revolve in the same direction shaft 2 remains stationary or is rotated in one direction or the other, depending upon the position of clutch 15.

Clutches 6, 7, 8, and 15 are automatically operated by the following-described mechanlsm: i

V16 is a shaft carrying upon it four camsurfaces 6, 7215, and 8a. This shaft will hereinafter, for the sake of brevity, be spoken of as the cam-shaft. The cam-surfaces act respectively upon pins 6b, 7b, 15b, and 8b in the ends of four clutch-levers 6c, 7C, 15C, and 8C. The other ends of these clutch-levers carry pins 6d, 7d, 15d, and 8d, respectively, which run in grooves 6E, 7 L, 15e, and 8e, respectively, in clutches 6, 7, 15, and 8. As cam-shaft 16 rotates cam-surfaces 6, 7 n, 15a, and 8 force clutch-levers 6C, 7C, 15C, and 8c to the right or left, thus throwing clutches 6, 7, 15, and 8 into or out of contact with the different gearwheels mounted upon shaft 2, and thus different parts of the printing mechanism are swung into or out of operative position. As shown in the drawings, the cam-surfaces are all arranged alike; but inmpract-ice, by means of clamps 17, upon which the cam-surfaces are borne, and nuts 18, they are so arranged upon shaft 16 as to time correctly the respective operations of the different parts, as will hereinafter be more fully described.

In order to prevent breakage of any of the parts in case a cam-surface should throw one of the levers over ata time when the projecting part of the clutch is not exactly in line with the recess in its gear-wheel, pins 6b, 7b, 15b, and 8b are each carried bya frame 27 is a shaft, hereinafter to be spoken of as the connecting-shaft, having at one end a beveled gear-wheel 28, meshing with gearwheels 22 22, and at its other end a worm 29, meshing with worin-wheel 30, loosely mounted upon shaft 16. Worm-wheel 30 carries a pawl 31, which engages with ratchet-wheel 32 upon shaft 16. Pawl 31 is held in engagement with ratchet-wheel 32 by spring Whichever one of gear-wheels 22 'm clutched and driven by shaft 2, connecting-shaft 27 is driven always in the same direction and, through worm 29,worrnwheel 30, pawl31, and ratchet- Wheel 32, it drives shaft 16 always in the same direction.

Shaft 16 has an extension 34, carrying on its end be veledl wheel 35,which meshes with beveled wheel 36 on one end of shaft 37. A beveled wheel 38 on the other end of this shaft meshes with'a beveled wheel 39 on ashaft 40. On the other end of shaft 40 a hand-wheel 40a 19, mounted upon a sliding har 2()I passing through openings on each side of the clutchlevers. Springs 21, upon sliding bar 20 on each side of frame 19, tend to keep the frame and pin in the center of the end of the clutch. The pins, frame, and sliding bar and springs form a yielding connection between the camsurface and the clutcli,which prevents breakage orstoppage of the parts until the projecting part of the clutch comes into line with the recess in the gear-wheel.

In the preferred form of my device shown in the drawings shaft 16 is driven by shaft 2 but as shaft 16 must always rotate in the same direction, and as shaft 2 rotates sometimes in one direction and sometimes in the other and sometimes not at all, I have devised the following-described mechanism to change the varying motion of shaft 2 into a motion in one direction only for shaft 16 and to permit shaft 16 to be rotated independently of shaft 2, either to enable shaft 2 to be started or for any other purpose:

Loosely mounted upon shaft 2 are two beveled gear-wheels 22 22, facing each other and each having a collar 23, provided with ratchetteeth, the teeth of one gear-wheel pointingin an opposite direction to those of the other gear-wheel. Upon shaft 2, between the gearwheels, are two collars 25, each provided with ratchet-teeth and facing the ratchet-collar 23 of one of the gear-wheels. The collars 25 are loose upon shaft 2 and are arranged in any suitable manner, as by spline and feather, so as to rotate with the shaft, while free to slide a shortdistancelongitudinallythereon. These collars are held toward the ratchet-collars 23 by coiled spring 26. As shaft 2 rotates in one direction the teeth of one of the collars 25 engage with the ratchet-teeth of one of theV gear-wheels and rotate that wheel, while the teeth of the other collar 25 slip over the teeth original positions.

or equivalent device is placed. adapted to be operated by hand. Whenever it is desired to turn cam-shaft 16 independently of shaft 2-as, for example, for the purpose of starting shaft 2 afs it lies at rest with clutch 15 in the center, midway between gear-wheels 1'4; 14-the hand-wheel on shaft 40 is turned and shaft 16 is rotated until clutch 15 is thrown into contact with one of the gear-wheels 14, when the controlling mechanism is at once started.

1 will now proceed to describe the operation of my improved device in its preferred form as applied automatically to a multicolor lithographic press, as illustrated in' the ligures upon Sheet 3 of the drawings. The cam-surfaces upon shaft 16 are adjusted so as to time the various movements to produce the following successive operations:

First operation-Shaft 16 is rotated by turning hand-wheel upon shaft LO until camsurface 15a, through clutch-lever 15C, throws clutch 15 to the right into contact with gearwheel 14. This rotates shaft 2 in a certain direction. At the same time cam-surface 6, through clutch-lever 6C, throws clutch 6 into contact with gear-wheel 3, and thus, through the train of gearing 3a, 3b, 3c, and 3d, swings damping-roller 3e into contact with printing or form cylinder 5d, thus dam pening that cylinder. Cam-surface 6a then causes clutch 6 to move away from gear-wheel 3. This operation is illustrated by Figs. 3 and 3b, first operation, and Fig. 3, on Sheet 3, and causes the printing-cylinder to be preliminarily dampened.

Second @Mahlow-Clutch 7 is then thrown by its cam-surface into contact with gearwheel ,and therebyink-rollers 4d 11d are swung against the form-cylinder, which is thereby inked. Clutches 15 and 7 then return to their This operation is illus- IIO IZO

l shaft 2, and at the same timel clutch 6 makes contact with gear-'wheel 3, thus withdrawing damping roller 3e from forrncylinder 5d.

' Clutches 15 and 6 are then withdrawn* to their original positions. This operation is illustratedfby Figs. and 5b, third operation, I The reason for this operation is' and Fig. 5a. because in the construction of parts illustrated in the drawings the printing-cylinder cannot be moved into contact with the impression-drum while the damping-rollers are in the position shown in Fig. 4b.I It is accordingly necessary first to remove the damping mechanism away from the printing-cylinder.

Fourth operation-Shaft 16 is then further turned by hand, clutch 15 is thrown to the right, andclutch 8 is thrown into contact with gear-wheel 5, swinging form-cylinder 5@ into contact with4 impression-cylinder 5"', `thus starting the printing operation. Clutch Sis then withdrawn from gear-wheel 5, while clutch 15 remains to the right. This operation is illustrated by Figs. 6 and 6b, fourth operation.

. Fifth operatton.-`-Clutch G is then Vthrown into contact with gear-wheel 3, thus bringing the'damping-roller again into ContactV with the form-roller. Clutch 6 is thenwithdrawn into its original position. 'This operation is illustrated by Figs. 7 and 7b, ifthoperation,

' and Fig. 7,

Sixth operation- Clutch 7 is moved into contact with gear-wheel 4, swinging theinking-rollers again into contact with the formcylinder. In this position of the parts the damping, inking, and printing operations are all proceeding at the same time. Clutches 1'5 and 7 are then withdrawn into their original positions. This operation is illustrated in Figs. 8 and 8b, sixth operation, and Fig.I 8?'.

The press is now in full operation, but theV motion of the cam-shaft has ceased.

In .the preferred form of my improvement all of the above steps except that of the starting of the first, third, and fourth operations, have been taken automatically through the action of the cams upon the cam-shaft. When it is desirable to stop the printing operation, the operator then turns the hand wheel.

clutches 6, 7, and 8 are alsomoved into contact with their respective gear-Wheels, when the form-cylinder and damping and inking rollers are all moved back into their original the ordinary operation of the press.

or rest positions. Thisoperation is illustrated in Figs. `Q'and 9b, and seventh operation.

' By my improved device in itspreferred form a complete, efiicient, and automatic control is maintained over the printing mechanism andthe operation'of printing-and the various steps are taken automatically and successively in their proper time and order.

' The 'cam-surfaces 6a, 7a, andSaare so arranged as to keep their respective clutches in contact with their respective gear-wheels for only such a vlength of time as is necessary to swing the damping or inking rollers or the form-cylinder from a position of rest to an operative position, or vice Versa.v Thecams upon the cam-shaft can of course be arranged and at different Vtimes from those above Set forth in the above-describedoperations.A

i The automatic movement` of the parts into or out of operative position is independent of Thus, for example, when the inking or damping mechanisms,or either of them,hasbeen moved out of operative position the press may still continue running, but no inking or damping, as the case may be, will take place, because such part or parts have been moved out-of operative position.

In the form of controlling-engine shown in the drawings the driving, mechanism of the controlling-engine consists of the shaft 2 and its connections. The source of power for the controlling-engine is the driving mechanism of the press, acting through shaft 12 and its connections. The connecting mechanism between' the driving mechanism of the controlling-engine and the damping-frames consists .of the train of gearingcompr'ising gear 3,

shaft 3a, and the other Agearing connecting said shaft 3a with the damping-frames. The connecting mechanism between the driving mechanism of the controlling-engine and the inking-frames consists of the train of gearing ,comprising gear 4, shaft 4a, and the other gearing connecting said shaft 4",With the inkframes. The connecting mechanism between the driving mechanism of the controlling-engine and the printing-surfaces consists of the train of gearing comprising gear-'wheel 5, shaft 5a, and the other gearing connecting said shaft with the printing-surfaces. The clutch mechanism to connect the source of power-the driving mechanism of the presswith the `driving mechanism of the controlling-engine consists ofthe two clutch gearwheels 14 and 14 and clutch 15. The clutch mechanism to connect the driving'mechan- Yism` of the controlling-engine with the convnectingnrnef'ihanism leading tothe damping- IOO IOS

IIO

gear-wheel et and clutch 7, and the clutch mechanism to connect the said driving mechanism with the connecting mechanism leading to the printing-surfaces consists of gearwheel 5 and clutch 8,.

In the drawings in this case my controllingengine has been shown as controlling the movements of the printing, inking, and damping devices only; but it can of course be applied to control the movements of any other part of the press which it may be desired to move.

The driving mechanism of my controllingengine may be driven from any suitable source of power, although I prefer to drive it, as shown in the drawings, by the driving mechanism of the press.

In the preferred form of my improved device as shown the connecting mechanisms intervening between the driving mechanism of the controlling-engine and the different parts of the press arel shown as consisting of trains of gearing; Such connecting mechanisms may, however, consist of any other form of mechanism suitable for the purpose. Likewise the means for operating the clutch mechanisms may be varied from those shown in the drawings.

My improved devices are simple in character, compact in form, and are easily operated. By means of them the movements of different parts of the press are easily, automatically, and Aquickly controlled, and the operator is enabled to move such parts automatically to any desired position with certainty and precision and to time such movements with exactness without any supervision other than is required to turn the handwheel to start the operations.

This application is designated as Gase B to distinguish it from two other applications for controlling-engines filed by me simultaneously herewith and designated as Case A and Case C.
